A quote from John MacArthur about objectivity:
Many who would call themselves Christians today are in precisely that situation. They use the language and symbolism of Christianity, but their real source of authority is something besides Scripture. Some simply live by their feelings and shape their beliefs in accord with their own personal preferences. Others actually claim God speaks directly to them through voices, strong impressions, or vague feelings which they interpret as direct revelations from the Holy Spirit. Still others think of the Scriptures as an improvisational script, which they can modify or interpret any way they please. In any case, their lives and beliefs are ordered in accord with their own personal preferences.
